Lets start with the HK. The HK can fire just about as fast as one can fire the trigger with 25 dmg a shot, clip of 20, not to mention its ability to one shot hs a person. In the very least the HK should not be a one shot hs, at most it should be take out completely. Next we got the DB. The DB is a wickedly OP shotgun that does way to much damage close up or far away for a shotgun that I couldn't accurately test its true damage. I personally think the BDs range shout be nerfed as it is way to far. These guns are far more OP then most guns in the almost all guns in the game right now and should be nerfed or taken out.
my boy what u fail to see is that the hk has no recoil while the deagle does, also the winchester cant fire as fast as u pull the trigger.
Theres only 1-2 DB's on a map, if the map even has it in the first place. The hk is easily countered. Strafe a fuck ton and make your movements unpredictable. With an ak you can take them out before they get the 3rd shot off. I wont be as harsh on you bc im literally watching bojack while typing this, anywho. The g3 is basically the lanky little brother of the hk. The winchesters fire rate is a hell of alot slower than others, and actually takes some decent skill to use and be good with it. The deagle... i dont know why you added that there but anyway. and the other winch, im assuming youre talking about the shotgun here, isnt op at all. hell if anything its quite underpowered in my opinion. ive never been able to 1 shot even with all pellets being headshots with this gun. 2-3 shots for a shotgun is a decent balance.
I don't think the HK SL8 is as overpowered as the Double Barrel, and even then I don't think the DB is that OP. The slow reload speed somewhat makes up for the ridiculous damage, but I do think that it spawns a little too often. I recall a game where I found 3 or 4 Double Barrels on Inno Motel... At one point it was as if every other player had one. The only problem I have with the HK is that its fire rate is a little too high with the reversion from the newer update. I'd say lower the fire rate and the spawning of the DB and it's good with me.
Let's set a weapon to deal 1 hp per bullet and can only shoot 1 bullet per minute. Furthermore, everytime you shoot, you have to reload afterwards. Let's see how op it is :^).
To be fair, I haven't seen either of them in use recently, except for Rice. So I wouldn't consider it a problem.
